Thank you!

Jake Lin

@JakeLin

can some one send me some test Zil? 8D2E6993903B29E98D59D01AEFD38BFABAC3A293 thanks

evesnow91

@evesnow91

@JakeLin Yea done

Jake Lin

@JakeLin

thanks

@evesnow91 I haven't got any? am i using the right network?

https://api.zilliqa.com/ is it right?

paladinlll

@paladinlll

maybe https://api-scilla.zilliqa.com/

Jake Lin

@JakeLin

thanks @paladinlll I have some zil on https://api-scilla.zilliqa.com/

evesnow91

@evesnow91

@JakeLin @paladinlll For the next testnet-v3 (https://api.zilliqa.com/) reboot next week, we will have the faucet ready to dispense ZILs for you guys to develop with. We will be scrapping https://api-scilla.zilliqa.com/ for developer usage.

Jake Lin

@JakeLin

So which one should I use? I think should be testnet-v3 (https://api.zilliqa.com/)

but I don't have zil on testnet-v3

Dan Ξ

@AndreiD

can anyone send me some ZILs for api-scilla ? f03ececc92a157aa4c3f26de32069749f7325bac

evesnow91

@evesnow91

Done

Jake Lin

@JakeLin

Hey guys, I just noticed I can't send token on testnet-v3, it was OK last night

solversa

@solversa

how many DAOs are already live on zilliqa ?

Edison Lim

@edisonljh

@JakeLin The testnet is undergoing maintenance. We will keep you posted once it's up.

@solversa Zilliqa is only going live in Jan 2019. So the answer is zero.

Jake Lin

@JakeLin

thanks

solversa

@solversa

@edisonljh How many are planned to be launched in Jan/Feb/March quarter, any idea ?

evesnow91

@evesnow91

Hi @/all, the Zilliqa Maoshanwang testnet at the endpoint https://api.zilliqa.com is up.
For future references, please use this status board to see the latest stats of the testnet.
We are working on a faucet now for this testnet. It will be accessible soon and its status will be included in the status board soon.
Please also do note that smaller scale (https://api-scilla.zilliqa.com) testnet has been scrapped.

@DuffleBag_Dul_twitter

need help building an app like uber but for a different puropse

join my team?

Dan Ξ

@AndreiD

why not a new facebook or a new youtube :))

Alexander Cyon

@Sajjon

@/all the latest release of the iOS Wallet is using the Staging Environment FYI. I will switch back to the prod testnet once it is up.

Anyway finally we have a name for the app - Zhip
(working title was Zupreme).

Download it from Testflight and after you have created (or restored) a Wallet request a payment and send me the link and I can send you some Staging testnet ZILs

Jake Lin

@JakeLin

Have we changed the get balance in https://api.zilliqa.com . before, it returned a zero balance if I check an account without any Tx. But now it returns

error:
code: -5
data: null
message: "Account is not created"

Micky Socaci

@mickys

yes it seems to have been changed to return an error if the account does not have a balance

Jake Lin

@JakeLin

thanks, Seems not quite right for a blockchain account for that behaviour

evesnow91

@evesnow91

If the account state is not initialised, it will return that error code. This error code is mainly for debugging purposes. But Say if I had 1000 ZILs and I spent all 1000 ZILs, it will return me 0 balance.

Jake Lin

@JakeLin

thanks for clarify that. In the other chain, e.g. Ethereum, it will return 0 balance without error. I will add some logic to handle that. Will it return 'code:-5' for that case? I need to use it to check and treat it as a OK case with no balance. thanks @evesnow91

Micky Socaci

@mickys

@JakeLin yeah it returns an error if the account has no state, but 0 if it has 0 balance :)

so just try / catch that

evesnow91

@evesnow91

We thought it might be necessary for some applications in future.

Jake Lin

@JakeLin

Hi guys, I have handled the 0 balance case, I am having another issue: when I try to send Zil using

const tx = await zilliqa.blockchain.createTransaction(
        zilliqa.transactions.new({
          version: 1,
          toAddr: sendTo,
          amount: new BN(sendAmount),
          gasPrice: new BN(sendGasPrice),
          gasLimit: Long.fromNumber(sendGasLimit),
        })
      );

I always got

error: {code: -26, data: null, message: "CHAIN_ID incorrect"}
id: 1
jsonrpc: "2.0"

can someone give me some hint?

I have seen this on Zilliqa-JS repo

// These are set by the core protocol, and may vary per-chain.
// These numbers are JUST AN EXAMPLE. They will NOT WORK on the public testnet
// or mainnet. Please check what they are before proceeding, or your
// transactions will simply be rejected.
const CHAIN_ID = 88;
const MSG_VERSION = 8;
const VERSION = bytes.pack(88, 8);

Jake Lin

@JakeLin

but don't know how to put the VERSION number

evesnow91

@evesnow91

Hey @JakeLin version is a decimal conversion of the binary concatenation of both CHAIN_ID and MSG_VERSION. You will need to pack them together. You can use the Zilliqa-js util package to do so.

const { BN, Long, bytes, units } = require('@zilliqa-js/util’);
…
const CHAIN_ID = 62;
const MSG_VERSION = 1;
const VER = bytes.pack(CHAIN_ID, MSG_VERSION);
…
    let tx = zilliqa.transactions.new({
        version: VER,
        toAddr: 'f8c429e096abaabf43257728894d88f1142501a1',
        // Note all transactional values has to be converted to Qa (the smallest accounting unit) when using the Zilliqa protocol.
        // 1 Qa is 10^-12 Zil.
        amount: units.toQa('1000000', units.Units.Zil),  // Sending an amount in Zil and converting the amount to Qa.
        gasPrice: units.toQa('1000', units.Units.Li), // Minimum gasPrice in Li. Convert to Qa.
        gasLimit: Long.fromNumber(1),
      });

Implementation in JS can follow @mickys format if you do not wish to use zilliqa-js utils package:

const CHAIN_ID = 1 // MainNet ID
const MSG_VERSION = 1 // First transaction payload version
const version = (( CHAIN_ID << 16 ) + MSG_VERSION).toString(); // returns 65537

Jake Lin

@JakeLin

I am using zilliqa-js utils package

Jake Lin

@JakeLin

@evesnow91 I have follow the example you provided above, I am able to tend Zil now, but I think the example is not right, because units.toQa('1000000', units.Units.Zil) will convert a huge number

for example, I try to send 1 zil, after amount: units.toQa(sendAmount, units.Units.Zil), it becomes 1000000000000, it means I send out 1000000000000 zil

evesnow91

@evesnow91

Hey it’s fine jake this is the unit account for zilliqa. Please see this forum post: https://forum.zilliqa.com/t/gas-accounting-in-zilliqa/199

Jake Lin

@JakeLin

Here is one of the payload in transactions

{"id":1,"jsonrpc":"2.0","method":"CreateTransaction","params":[{"version":4063233,"toAddr":"399667D8c48cefBF1972F0C12eB49c8Ab995dd97","nonce":4,"pubKey":"0325304d408cf4b3e0eb9bba264c7eb78a2f54de65b608d07872f827af2d0a9b4b","amount":"1000000000000","gasPrice":"1000000000","gasLimit":"1","code":"","data":"","signature":"1d36bf20aea6cb59e224291d4cc2a07bdbe6d0c220ed3525d31bea0162f0bf1c764ed4f020c7036272059f5378aa86beac21eef4cdabe2ae90b91384eae9a227"}]}

evesnow91

@evesnow91

They are in the smallest unit Qa, similar to ethereum Wei

Jake Lin

@JakeLin

I understand the usage of Qa, but when I send out "amount":"1000000000000" in the payload, I send out 1000000000000 zil not 1 zil

Micky Socaci

@mickys

amount: units.toQa('1', units.Units.Zil) << you send 1 zil, that is 1 000 000 LI ( 10 pow 6 ) or 1 000 000 000 000 QA ( 10 ** 12 ) :)

Jake Lin

@JakeLin

I understand that
